Have you designed a bitboard? Yes..Skip the reading..:) Guys I am happy to start “backToBasics series” for java and related technologies. The bitwise operators mostly used for setting individual flag bits in value, prerequisite for following explanation is binary numbers and 2’s complement representation. The bitwise shift operators are : >> , << , >>>…
Few days back I posted the comparison table which describes the various features/characteristcs of different free or open source databases, this would help us to understand the various free/open source database offerings. Could help us to decide the database selection for our next project. I have used postgreSQL, MySQL and HSQLDB now looking forward to…

The nature of the ESB is distributed; ESB is more scalable than the hub-and-spoke architecture.

EAI/hub-and-spoke solutions are generally based on proprietary standards.
An Enterprise Service Bus (ESB) can have either a traditional hub-and-spoke architecture or a distributed, peer-to-peer architecture. Hub-and-Spoke systems are easy to administer but difficult to scale, since as processes are added the hub becomes a communication bottleneck. Most ESB’s are based on a peer-to-peer architecture allow hardware resources scattered across the network to be…
